定义类别工具箱

类别工具箱包含多组积木，这些积木按不同类别排列。

如需创建类别工具箱，请将描述工具箱的 JSON 或 XML 传递给配置选项的 toolbox 属性。

JSON

var toolbox = {
    "kind": "categoryToolbox",
    "contents": [
      {
        "kind": "category",
        "name": "Control",
        "contents": [
          {
            "kind": "block",
            "type": "controls_if"
          },
        ]
      },
      {
        "kind": "category",
        "name": "Logic",
        "contents": [
          {
            "kind": "block",
            "type": "logic_compare"
          },
          {
            "kind": "block",
            "type": "logic_operation"
          },
          {
            "kind": "block",
            "type": "logic_boolean"
          }
        ]
      }
    ]
  };
var workspace = Blockly.inject('blocklyDiv', {toolbox: toolbox});

XML

<xml id="toolbox" style="display: none">
  <category name="Control">
    <block type="controls_if"></block>
  </category>
  <category name="Logic">
    <block type="logic_compare"></block>
    <block type="logic_operation"></block>
    <block type="logic_boolean"></block>
  </category>
</xml>
<script>
  var workspace = Blockly.inject('blocklyDiv',
      {toolbox: document.getElementById('toolbox')});
</script>

XML 字符串

var toolbox = '<xml id="toolbox" style="display: none">' +
    '<category name="Control">' +
    '<block type="controls_if"></block>' +
    '</category>' +
    '<category name="Logic">' +
    '<block type="logic_compare"></block>' +
    '<block type="logic_operation"></block>' +
    '<block type="logic_boolean"></block>' +
    '</category>' +

var workspace = Blockly.inject('blocklyDiv', {toolbox: toolbox});
